基于springboot搭建dubbo框架(注解和xml配置两种方式)

来源：互联网发布：部队网络安全教育编辑：程序博客网时间：2024/06/05 14:18

一.基于SpringBoot的xml开发

1.新建maven工程

新建三个maven工程(工程名字是现在项目的名称随便命名的)

2.本地启动zookeeper

3.启动provider和consumer应用

访问http://localhost:8081/products/10001

浏览器返回

{"id": "10001","name": "Honor V10","price": 2699.0,"category": "TEL","brand": "HUAWEI"}

二.基于SpringBoot的注解开发

新建三个maven工程(工程名字是现在项目的名称随便命名的)

注意:

第一个xml方式中引入dubbo一定要排除spring依赖,否则启动失败
